  • the invention relates to a laundry drum for a laundry treatment machine with a drum shell having circumferentially distributed structures that arise from the cylindrical shape of the mounted in the laundry drum drum shell.
  • a laundry drum is known from DE 44 37 986 A1.
  • structures in the jacket sheet of a laundry drum in the form of staggered quadrangular or hexagonal arch surfaces are shown therein.
  • Such structures have been used in laundry drums mainly because they give the structured jacket sheet on the one hand a certain dimensional stability, which affects above all in a reduced acoustic tendency to oscillate.
  • such a structure also has a certain decorative effect.
  • the invention has for its object to find a casing sheet structure for a laundry drum described above, on the one hand has the advantageous properties of structures of the prior art, but in addition also provides a basis for their training for favorably influencing the mechanical laundry treatment during the rotary motion the drum.
  • this object is achieved by the characterizing part of claim 1 in such a way that the structures are formed from line-shaped elevations extending in the circumferential line and curved inwards.
  • Such surveys can in fact - as will be explained below - in form many ways so that they have a beneficial influence on the mechanical laundry treatment during the drum rotation. Since they also stabilize the drum shell to such an extent that the material used for the drum plate can be reduced to a minimum, that no acoustic oscillation tendencies are to be feared and that the surface properties of such a shaped lateral surface are ideal for the laundry treatment, an inventively designed laundry drum is an optimum represent for use in the laundry treatment.
  • the elevations can follow straight lines that extend at least partially parallel or not parallel to each other and / or the circumferential direction of the drum.
  • the line-shaped elevations may be closed or interrupted in the circumferential direction. They may have equal or unequal distances to each other and may be the same or at least partially unequal or different in width.
  • at least a part of the flood holes can be mounted in one or both flanks of the elevations. Other flood holes may be located in the areas of the drum shell that are outside the elevations.
  • 1 is a perspective view of the front side of a laundry treatment machine, with free insight into the laundry drum, the jacket plate is provided on the inside with linear elevations, 2 shows a cross section through a jacket plate parallel to the axial direction of the laundry drum with line-shaped elevations,
  • FIG. 3 shows a cross section as in FIG. 2 with other distances of the linear elevations
  • FIG. 4 shows the view from outside onto a jacket plate with in-phase wave-shaped elevations and a cross section through such a jacket plate parallel to the axis direction A-A of the laundry drum.
  • FIG. 4 outer view and cross section corresponding to FIG. 4 with unparallel and different wide undulating elevations
  • FIG. 6 external view and cross section corresponding to FIG. 4 with parallel and in-phase but unequal width undulating elevations
  • FIG. 6 external view and cross section corresponding to FIG. 4 with parallel and in-phase but unequal width undulating elevations
  • FIG. 7 outer view and cross section corresponding to FIG. 4 with curved, helically arranged and differently wide elevations

  • FIG. 11 outer view and cross section corresponding to FIG. 4 with wave-shaped elements arranged parallel to one another but offset from one another
  • FIG. 1 is shown as a laundry treatment machine, a washing machine, which is attached to the front side 1 feed opening 2 with the door removed gives an insight into the interior of the laundry drum 3.
  • a washing machine which is attached to the front side 1 feed opening 2 with the door removed gives an insight into the interior of the laundry drum 3.
  • It has a cylindrical drum shell 4, on the inside of several Wäschemit Meeting 5 are evenly distributed.
  • the drum shell has 4 inwardly bulging line-shaped elevations 6, which will be explained in more detail with reference to the following figures.
  • these elevations ensure that the drum shell becomes a structure which is resistant to mechanical vibration, thereby avoiding otherwise feared acoustic disturbances.
  • material can be saved with smaller wall thicknesses of the drum shell 4 and, as will be shown below, achieve a particularly gentle surface design which nevertheless produces an increased mechanical washing effect.
  • linear elevations 6 can assume a shape as shown in FIG. 2 or 3 when viewed in cross-section of the sheet of such a drum shell 4.
  • the elevation 6 gradually swings inward from the cylindrical shape of the region 7 of the drum shell 4, forms a soft ridge line 8 and also swings softly back into the cylindrical shape of the region 7.
  • the remaining in the cylindrical shape areas 7 can in a laundry treatment machine, which requires no fluid exchange for the treatment process, - as shown - remain closed.
  • flood holes In a laundry treatment machine, which exchanges liquids between the laundry, the drum interior and the laundry drum surrounding space for the treatment process -. B. in a washing machine -, can in the cylindrical areas so-called flood holes may be appropriate. Such flood holes are notorious, but not shown in Fig. 1 to 3 for reasons of simplicity.
  • the distances B of the elevations 6 in Fig. 2 are equal to each other, in contrast to the elevations 6 in Fig. 3, whose distances C and D are unequal. This may play a role in such treatment processes where the laundry within the drum is unevenly distributed during its rotation.
  • the fragments of drum shells 4 are shown as substantially flat flat bodies, which can be redesigned by forming into a cylinder into a laundry drum. Notwithstanding the examples in FIGS. 2 and 3, the elevations 6 also do not swing upwards gradually out of the cylindrical regions 7; because they are delimited to the areas 7 by a relatively sharp bending edge 9.
  • the elevations 6 and their arrangement to each other differ on the one hand from those of Figs. 2 and 3 on the other hand but also from one embodiment to another embodiment.
  • FIG. 4 shows a drum shell 4, on the inside of which bulge bulges 6 bulge in a closed circle along the peripheral line 40 and loop around the drum shell.
  • the ridge lines 10 of the elevations follow a similar to the sinusoidal vibration with a phase length P and a vibration width W. phase length P and vibration width W can be varied as needed and trial taking into account the mechanical washing action.
  • the areas 7 of the drum shell each contain a number of flood holes 11. If the laundry drum equipped therewith is not provided for a liquid-conducting laundry treatment machine, the flood holes 11 can be omitted. This applies equally to the drum shells below.
  • the drum shell 4 shown in Fig. 5 also has linear elevations 6. Adjacent areas 7 between the surveys but do not run parallel to each other. Their main axes are at an angle ⁇ «100 ° or ß « 80 ° to the drum axis AA, which deviates from the right angle.
  • phase length P and the oscillation width W in this example are similar to those of FIG. 4. Touch gene side, they can reverse their angular position ⁇ and ß and thus the elevations 6, which have the greatest width and height at the point of closest proximity of each of the adjacent areas 7, narrow again in the course. Instead, however, the elevations 6 may simply be limited in their length, and thus the areas 7 are connected between the boundaries.
  • the angular positions of the major axes of the regions 7 can - as of course, the phase lengths and vibration lengths - be varied according to need and trial.
  • the drum shell 4 in Fig. 6 is very similar to that in Fig. 4.
  • the phase lengths of the elevations 6, 16 and 26 are greater than in Fig. 4.
  • the mutually parallel regions have 7 different distances B, C. and D, so that the intervening bumps 6, 16 and 26 are different in width.
  • the elevations 6, 16 and 26 have almost the same heights with each other, so that the elevation 6 is perceived flatter than the elevations 16 and 26, the curvature of their curvature is only lower. Again, the same variations are possible as in the previous and in the following examples. This includes variations in the heights of the surveys 6, 16 and 26, respectively.
  • the elevations 18 have approximately the same length of phases P as the sinusoidal elevations 6 of FIG. 4.
  • the oscillation width W is slightly larger.
  • This type of elevations 18 are formed by zigzag-shaped cylindrical regions 7 of the drum shell 4. bordered elevations 18, whose ridge lines 19 also follow almost a zig-zag line. However, the sharp corners of a zigzag line are rounded.
  • the cylindrical regions 20 have no flood holes here. However, using a fluid interposed between the interior and the exterior of the drum would create flood holes in those areas 20.
  • the conditions are reversed compared to the example of FIG. 9.
  • the cylindrical portions 7 oscillate in the opposite phase, while the projections 6 become narrower and wider along the circumference.
  • the curvature of the elevations 6 remains constant along the circumferential line, the bulges 22 and 23 are sometimes higher and lower, so that alternately high and low bulges 22 and 23 are formed, which, in addition to the carriers 5 (FIG. Fig. 1) exert a mechanical effect on the laundry.
  • Fig. 12 still demonstrates how a drum shell 4 may look, whose elevations 25 are finite, so that each elevation 25 is surrounded by a cylindrical portion 27.
  • the attachment of a larger number of flood holes 11 is possible, so that the liquid exchange can be intensified.
  • the common Alternate contact of the laundry with different bulges of the elevations 25 also reinforces the mechanical washing action.
  • the regularly arranged in the cylindrical regions 7 flood holes 11 may deviating from the embodiments shown either additionally o- only in such flanks of elevations 6, 16, 18, 25, 26, 36, 46, 56 o- 66 attached be who put themselves while turning the laundry drum against the liquid flowing into it.
  • the flanks of the elevations 36, 46, 56, and 66 of FIG. 7 are ideally suited for this, because they have partial regions that are almost transverse to the moved liquid. But even those parts of the elevations in the other figures, which have at least one not too small skew angle with respect to the liquid movement, which will usually be the movement in the circumferential direction, may have flood holes 11 in these parts of their flanks.
